OF SAME PLACE.

IMPROVEMENT IN EARTH-AUGERS.

Specification forming part of Letters Patent No. 178,675, dated June 13, 1876; application fi ed February 28, 1876.

To all whom it may concern:

contrived in three equal sections, by which the auger works faster, and by taking out one of the borin, 3,'-bitsv and bucket-sections and substituting a pronged bit of peculiar form, with a shorter bucket-section, bowlders of larger size may be taken out than can be with other angers.

Figure 1 is a sectional elevation of my improved well-auger. Fig. 2 is a horizontal section taken on line 00 0c of Fig. 1, and Fig. 3 is an elevation of the pronged bit for taking out stones. 7

Similar letters of reference indicate corresponding parts.

A represents the three sections forming the auger-bucket, two ot'which are permanently connected to the auger-shaft B, while one is detachable for changing it for the section 0, having the pronged bit D ibr taking out stones, the detachable section being attached by the beveled shank, having studs F fitting in the I crotch G of the shaft, and. being secured by the slides I I, and the crotch being notched at K, (dotted,) to receive the studs, to prevent the section from dropping out. The bucketsections A are bent at the lower end, as shown at L, and the bits H. are lapped on and bolted thereto, so that the strength of both plates is utilized for driving the bit into the earth. The pronged bit D for taking out stones is attached to a shank, J, which bends around from the.

side of the line of the bore into the bucket,

thus enabling obstructions to be removed, which, 'with otheraugers, would cause the abandonment of the well.

, Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The prong-bit D, attached, by a shank, J,

to a short bucketsection, O, which shank is arranged to support the bitin relation to the bit surrounding it, as described.

2. The detachable bucket-section, connected to the shaft by the beveled shank E, having studs F fitted in the crotched shaft, having notches for the studs, and secured by the slides I I, substantially as specified.
